In the last episode, we dug deep into the underpinnings of optimistic concurrency handling in EF Core. In this episode, we continue that journey to cover disconnected scenarios. That is, where the entity travels to a client and then back to the server before being updated in the database. We’ll look at the different patterns for doing updates like this in ASP.NET Core and Blazor apps and see how concurrency tokens work with each of these. We’ll also look at how `ExecuteUpdate` can be used with concurrency tokens, and take a look at ETag concurrency in Azure Cosmos DB.
